The use of radiographs for assessment of asymmetric growth in mandible with AAI. One patient's view report

The indices of asymmetry enable estimation and long-term control of mandibular growth. The aim of this study is to present 3 indices which have been used in case of atypical growth of left and right part of mandible. Radiograms in PA projection, panoramic views and CT scans of patient KK, aged 24, were used in this study. Comparative measurements and calculations of Habets index, Kjellberg index and own, angular asymmetry index (AAI) were performed. The analysis of left mandibular condyle and ramus showed severe anatomical deviations. Comparative evaluation of panoramic views allowed to observe progression of lesions responsible for asymmetry. Indices of asymmetry are objective method of mandibular growth estimation. Because of different gauge points and different way of calculation, presented indices: Habets, Kjellberg and AAI are incomparable, but each of them may be used as sufficient diagnostic tool. The angular asymmetry index (AAI) seems to be the simplest and quickest of all three. (author)
